A while back we had a hen manage to scratch & squeeze her way out of the tractor where our Spaniel got to her. She had some plucked areas and a couple of areas of torn skin . She is well on her way back to 100%. We attempted to re-introduce her back to her old flock friends, but within seconds the other hens were on her and going for her new feathers. What is the proper way to get them all back together? Right now we have 5 laying and the one that follows us around the yard like a puppy... Thanks!
